The component development status of HL-2M tokamak

HL-2M is a medium-sized copper-conductor tokamak under construction at the Southwestern Institute of Physics (SWIP). HL-2M project will construct a totally new tokamak machine, with other system upgrades from present existing tokamak at SWIP. The project is progressing. The machine components, coils, vacuum vessel, support, etc. are in the stage of fabrication in factories and to be delivered sequentially in next year for tokamak assembly. The scheme of machine assembly has been made. Other components or systems involved go forward into different construction stages. The progress of the component developments is mainly presented.
